The majority of Class ¥² malocclusion have maxillary retrusion. Thus, it becomes
obvious that management of most skeletal Class ¥² malocclusion cases should include
maxillary protraction as major objective. Additionally, in Class ¥² malocclusion with
posterior crossbite, RME 'disarticulates' the maxilla and initiates cellular response in the
sutures, allowing a more positive reaction to protraction forces. Using facemask with
RME helped in correction of skeletal Class ¥² malocclusion by the anterior displacement
of maxilla and maxillary dentition, and changing the direction of the growth of mandible.
Thus, acceptable improvement in the Class ¥² profile was performed.
